• How to: Retrieve data on a hard disk of laptop after screen went kaput

  Original title: my computer screen dell laptop went kaput can I connect my laptop it to my office to recover files etc my computer laptop OS is vista and my office windows 7?

  I have a dell laptop where the screen is dead? I connected to an external display of phillips, who worked for awhile, but which has now gone empty as well.

  How can I transfer files etc. to my desktop from the laptop? the operating system vista laptop and the pc is windows 7.

  Any help would be appreciated.

  Hello frechjohn,

  Your best bet to solve this will probably be in getting a USB drive cage to put laptop hard drive.  Once this is done, you can plug the USB cable into your desktop computer and browse the structure of folders and files on the drive of the laptop.

  You can find these stores to the hardware of the computer.

  The easiest way would be to put his HARD drive in a box that connects to the computer by USB.

  This is just an example - http://www.amazon.co.uk/Hard-Drive-Caddy-Case-Enclosure/dp/B003MVW2SM

  You probably have a 2.5 HDD "because I know that all laptops do.  If you need to buy an enclosure for a 2.5 drive "[not a disk 3.5" that could come from a desktop computer].

  Almost all cases derive the power to drive the HARD drive to the USB itself [rather than an external power].  If you see one that needs an external power supply, then you are probably looking to the wrong thing.

  You need to know if the HARD drive is IDE or SATA.  It depends on the age of the computer.  Your computer's manual should tell you or you can whip the HARD drive just to have a look.

  • Here is an illustration of an IDE - http://www.amazon.co.uk/Generic-Toshiba-Fujitsu-Samsung-Hitachi/dp/B0042WZZD4/ref=pd_sim_147_4?ie=UTF8&dpID=21bYEH0CONL&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&refRID=125C3XKTAFS54XACCCZ8 - connection if you look at the diagrams that you will see that there are long rows of pine trees coming from the HARD disk - what is FDI.
  • Here are illustrations of a connection SATA - http://www.amazon.co.uk/Screw-drive-Enclosure-laptop-Laptop/dp/B003RIL0EM/ref=pd_sim_147_2?ie=UTF8&dpID=419CrJiBX9L&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&refRID=125C3XKTAFS54XACCCZ8 and http://www.amazon.co.uk/drive-Enclosure-laptop-Caddy-Laptop/dp/B00926NM8K/ref=pd_sim_147_9?ie=UTF8&dpID=31sO4aOkykL&dpSrc=sims&preST=_AC_UL160_SR160%2C160_&refRID=125C3XKTAFS54XACCCZ8 - the diagrams show the link inside that connects the HARD drive on [if it's a reflection of what sticks out from HARD drive]-you can see that the connection is a long slot in two sections to the HDD has a long protruding into two sections - which is SATA.

• How to insert data into tables using sql loops

  Oracle 10.2 g

  now

  Why I'm doing this instead of

  create table student(no,id)

  This will cause the duplication of the upn
  
  using separate throws an error.

  Thank you.

  Hello

  As you discovered, you cannot use SELECT DISTINCT and sequence. NEXTVAL in the same query.

  You can SELECT DISTINCT in a subquery, like this:

  CREATE TABLE     student
  AS
  WITH     distinct_ids     AS
  (
       SELECT DISTINCT     student_id     AS id
       FROM     students_table
  )
  SELECT     st_seq.NEXTVAL     AS st_id
  ,     id
  FROM     distinct_ids;

  This plan gives you an idea of why your initial synchronization has been long - most of your readings are one-piece readings and you have read 53 724 blocks. If you estimate 1 centisecond by read (which could be on a reasonable charge system) then it is 537 seconds. to 5 milliseconds per read, it's still 268 seconds or 4 minutes and 30 seconds.

  A quick break down of some (the worst case) potential time - only you can say whether or not some of these readings will be always/often/never being cached in the file or at the SAN level.

  Line 11 - physical reads 6 400 done - it's a tree bitmap then the readings are in the order of physical table with no. rereads. Call 5ms by read-online 32 seconds. L

  | * 11 |            TABLE ACCESS BY INDEX ROWID | DSCLR                       |      1.   5079.   158K |   533 (1) | 00:00:08 |  91395 | 00:00:01.27 |    6460.   6400 |       |       |          |

  The hash join takes us from 6 400 to 11 788 because it joins, lines 21 to 25 (nested loop) in which most of the work is the random access table with some automatic caching: 26 seconds. Do a search here rather than indexed 22 000 access? Which would be faster, which would charge less.

  | * 25.             TABLE ACCESS BY INDEX ROWID | OCRN                        |  22050.      1.    21.     1 (0) | 00:00:01 |  21059 | 00:01:04.74 |   15634 |   5280.       |       |          |

  Three nested loops that introduce more readings:

  11788 9-> 26386:14 600 of the predicate view pushed which some lies but a very large index and a table of random access 73 seconds

  8 26386-> 33783:7 400 index line 30 - big clue about 37 seconds Access hides

  33783 7-> 53691:19 900 31 table access - large table line, not much caching, 100 seconds.

  In each case, you can ask if an analysis would take less time than all of these random reads.

  NOTE - all I'm pointing our here where you potentially use a lot of time so that you can ask whether or not you should do little of the query in this way, or if there is an alternative, or if the work you're doing is absolutely necessary. If you want to optimize the query you should consider the intent of the query and think your way through a reasonable join order to see if you can imagine an effective way to get the same data. I have written a few articles and presentation on an approach that begins by drawing - here is a link to an article I wrote for a group of SQL Server: https://www.simple-talk.com/sql/performance/designing-efficient-sql-a-visual-approach/

• Need help for the conversion of the nested loops to use the stream

  I'm trying to teach me how to effectively use the java stream, but finds it difficult to find the correct syntax for a problem of nested loop. I would like to convert the following code to use the Java 8 stream instead of nested loops.  Can anyone provide an example or a solution?

   /**
       * Return all members of stringListOne that begin with any of the strings in
       * stringListTwo
       *
       * @return all members of stringListOne that begin with any of the strings in
       * stringListTwo
       */
      Set<String> getFilteredStrings(Set<String> stringListOne, Set<String> stringListTwo) {
       
        Set<String> stringListOneFiltered = new HashSet<String>();
        for (String next : stringListOne) {
              for (String nextPrefix : stringListTwo) {
                  if (next.startsWith(nextPrefix)) {
                      stringListOneFiltered.add(next);
                  }
              }
          }
          return stringListOneFiltered;
      }
  

  Here's a test case for the above code:

  /**
       * Test method for {@link scratchpad.MyClass#getFilteredStrings(java.util.Set, java.util.Set)}.
       */
      @Test
      public final void testGetFilteredStrings() {
  
          MyClass uut = new MyClass();
          
          Set<String> stringListOne = new HashSet<String>();
          stringListOne.add("until");
          stringListOne.add("unite");
          stringListOne.add("under");
          stringListOne.add("prepare");
          stringListOne.add("pretend");
          stringListOne.add("prefix");
          stringListOne.add("prepend");
          stringListOne.add("post");
          stringListOne.add("positive");
          stringListOne.add("postgame");
          stringListOne.add("postpone");       
          
          Set<String> stringListTwo = new HashSet<String>();
          stringListTwo.add("post");
          stringListTwo.add("pre");
          stringListTwo.add("und");
          
          
          Set<String> result= uut.getFilteredStrings(stringListOne, stringListTwo);
          
          System.out.println(result);
          assertEquals(8, result.size());
      }
  

  Thanks for any help you can provide!  I get the hang of using the course of water, but this particular code was difficult.

  tmbc

  I found the following solution to my question:

  GetFilteredStrings (Set stringListOne, the value

  {Set stringListTwo)

  Predicate startsWith = p-> stringListTwo.stream () .anyMatch (prefix-> p.startsWith (prefix));

  Return stringListOne.stream () .filter (startsWith) .collect (Collectors.toSet ());

• How to create a chart using two independent loops while?

  Hello world

  I'm currently developing a program for the acquisition of data. In this program, I have two independent, while loops that each output a number of type double with each iteration of the loop. I am able to successfully create two independent waveform graphs (data / time) for each of the loops when placed inside. However, I now want to create a live data xy chart (the output of a loop is x and the output of the other is there).

  I have a problem, that the distinct nature of loops... When I try to extract data outside of the loop (naturally), it is not refresh with each iteration of the loop causing the graph xy does not work in the way I intend. Is there an easy way to solve this problem? If more clarification is needed, please let me know!

  David

  If the two loops are not synchronized, exactly how do you do the xy graph, where each point, by definition, must have a value of each loop.

  1. updated when updates or the other value and combine with the last value from the other loop?
  2. updated on a constant basis with the current value of each loop?
  3. ... There are many other possibilities.

  #2 is the easiest. Simply create a third loop with a reasonable time and graph the two values via local variables. You probably also should limit the history of ranking somehow.

• How to send the SQL for SQL Server statement and return data without using database connectivity Kit?

  Hi, I tried to figure out how to extract data from my SQL Server databases and reading messages and to do some tests with examples, I can get data connection type in my SQL server, but so far nothing helps.  Is it possible to get data from a SQL Server database without using the database connectivity Toolkit?  and if so, how?  are there whitepapers and/or examples of this?  So far, I can't find something that works.  Thank you.

  Jesse - what is your reason for not using the database connectivity Toolkit? It is by far the best way to recover the data.
